Jimmy Moore: Quite frankly. They’ve not been trained to teach you how to do nutrition, and then if they turn to nutrition they either leave it to the dietitian who has been trained in low fat, high carb diets or they’ll just “Well, the USDA my plate says blah blah blah.” They’re just parading what someone else has said. They’ve not done their own research. Just assuming that your doctor knows everything about what it takes nutritionally to make you healthy is a bad mistake.
Children who discontinue the diet after achieving seizure freedom have about a 20% risk of seizures returning. The length of time until recurrence is highly variable, but averages two years. This risk of recurrence compares with 10% for resective surgery (where part of the brain is removed) and 30–50% for anticonvulsant therapy. Of those who have a recurrence, just over half can regain freedom from seizures either with anticonvulsants or by returning to the ketogenic diet. Recurrence is more likely if, despite seizure freedom, an electroencephalogram shows epileptiform spikes, which indicate epileptic activity in the brain but are below the level that will cause a seizure. Recurrence is also likely if an MRI scan shows focal abnormalities (for example, as in children with tuberous sclerosis). Such children may remain on the diet longer than average, and children with tuberous sclerosis who achieve seizure freedom could remain on the ketogenic diet indefinitely.
A small Feb. 20, 2017, study looked at the impact of a six-week ketogenic diet on physical fitness and body composition in 42 healthy adults. The study, published in the journal Nutrition & Metabolism, found a mildly negative impact on physical performance in terms of endurance capacity, peak power and faster exhaustion. Overall, researchers concluded, “Our findings lead us to assume that a [ketogenic diet] does not impact physical fitness in a clinically relevant manner that would impair activities of daily living and aerobic training.” The “significant” weight loss of about 4.4 pounds, on average, did not affect muscle mass or function.
When you eat less than 50 grams of carbs a day, your body eventually runs out of fuel (blood sugar) it can use quickly. This typically takes 3 to 4 days. Then you’ll start to break down protein and fat for energy, which can make you lose weight. This is called ketosis. It's important to note that the ketogenic diet is a short term diet that's focussed on weight loss rather than the pursuit of health benefits.
Yes. There is growing evidence showing its usefulness in controlling seizures in adults with medically refractory epilepsy. While some adults may be started on classic ketogenic diet, others will be trained in the modified ketogenic or atkins diet which allows more freedom in dietary choices, and affords them the ability to still enjoy going out to restaurants while maintaining this diet therapy. With proper training and motivation, adults can successfully remain on this diet and gain good control of their seizures. Despite some of the adult ketogenic diets offering a little more flexibility it is still considered a medical therapy and should be initiated and maintained by your medical team.
Mitochondria generate reactive oxygen species (ROS) during their metabolic activities. In normal cells, the production of ROS and their elimination by antioxidants are kept in balance.10 Intriguingly, a higher incidence of errors, or mutations, in mitochondrial DNA have been observed in many human cancers, likely as a result of uncontrolled ROS production and oxidative stress.11
The ketogenic diet has been studied in at least 14 rodent animal models of seizures. It is protective in many of these models and has a different protection profile than any known anticonvulsant. Conversely, fenofibrate, not used clinically as an antiepileptic, exhibits experimental anticonvulsant properties in adult rats comparable to the ketogenic diet. This, together with studies showing its efficacy in patients who have failed to achieve seizure control on half a dozen drugs, suggests a unique mechanism of action.
Another difference between older and newer studies is that the type of patients treated with the ketogenic diet has changed over time. When first developed and used, the ketogenic diet was not a treatment of last resort; in contrast, the children in modern studies have already tried and failed a number of anticonvulsant drugs, so may be assumed to have more difficult-to-treat epilepsy. Early and modern studies also differ because the treatment protocol has changed. In older protocols, the diet was initiated with a prolonged fast, designed to lose 5–10% body weight, and heavily restricted the calorie intake. Concerns over child health and growth led to a relaxation of the diet's restrictions. Fluid restriction was once a feature of the diet, but this led to increased risk of constipation and kidney stones, and is no longer considered beneficial.
Therefore, when you’re following a ketogenic diet plan for beginners, your body is burning fat for energy rather than carbohydrates, so in the process most people lose weight and excess body fat rapidly, even when consuming lots of fat and adequate calories through their daily food intake. Another major benefit of the keto diet is that there’s no need to count calories, feel hungry or attempt to burn loads of calories through hours of intense exercise.
Ketosis: What is ketosis? Ketosis is a metabolic process, and it involves the body burning stored fat instead of glucose. Some people try to induce this with a low-carb diet, which can be healthy. However, ketosis also produces acid, and high levels of this can cause severe complications, especially for people with diabetes. Learn more here. Read now
Then you’ve got "keto-approved" junk foods like cookies, candy, and bread that promise to keep you in ketosis even as you indulge in your favorite comfort foods. The flip side is ketogenic diets that include almost no plant foods, focusing instead on meat, meat, and more meat. Bring on the bacon. Slather your steak in butter. Who needs vegetables? (Hint: You do!) Ketogenic diets are a practical invitation for vegetable-phobic people, and when you skip out on gut-healing plant foods, you create microbiome mayhem.
The most common side effect encountered is constipation. Many of the children who begin the diet are already prone to this problem because of limited mobility, hypotonia, or spasticity. Constipation can be treated with regular doses of polyethylene glycol, fiber, increased fluids, salt, mineral oil, intermittent pediatric-dose enemas, or magnesium hydroxide . Other more common side effects include hunger, acidosis (during illness), and hypoglycemia (just during the start of the diet). Many children as well can have gastroesophageal reflux, which can be managed with medications. The high fat content decreases gastric emptying, which promotes gastroesophageal reflux.
For example, a pretty large number of animal studies have shown that a ketogenic diet can reduce tumor growth and improve survival rates. There was one 22-day study in mice that looked at the differences between the ketogenic diet and other diets. That study found that a ketogenic diet reduced tumor growth by up to 65% and nearly doubled survival time in some cases.
Any recommendations on cookbooks? I just purchased Simply Keto and the author uses what seems an abundance of processed meats which have highly toxic cancer causing sodium. Also, the sweeteners suggested rather then sugar are also highly toxic cancer causing…and so on. I am trying to cancel my order so I can research more on recipes, using foods that truly are healthy and not causing cancer in itself, losing weight is not my priority and seems these cookbooks are more focused on losing weight not fighting cancer. The list of foods provided could not be complete, so if you are going to guide people to Keto lifestyle (I hate using the word “diet”) please provide more information such as those in the know and can trust recipes and guidance with complete list of foods and so on. Thank you in advance.
In other words, clinical data should be rolling in fairly soon, and that’s a good thing. In the meantime Dr. Seyfried and other advocates who so passionately believe that ketogenic diets will greatly help patients with brain cancer do no one any favors by claiming unequivocally that cancer is a metabolic disease and saying that ketogenic diets are more beneficial than chemotherapy for patients with brain tumors.
Dominic D’Agostino has argued that the mutations that are often observed in cancer may be secondary to mitochondrial dysfunction because injured mitochondria produce volatile compounds called reactive oxygen species (ROS), and these ROS can damage DNA. In this view, it may be that mitochondrial dysfunction comes first, and then that’s what leads to the mutations that are often observed in cancer.
Hello, following a Keto diet with IF but cholesterol ratios not proper. Diet fats come mainly from olive oil, avocado oil, once a week beef, no butter, bacon etc. Had to go back on statins. Goal is stay away from drugs. Is there a doctor/clinic in the Boston area that you can recommend that understands/tests what you explain in this article? Please advise.
Wondering how many carb foods you can eat and still be “in ketosis”? The traditional ketogenic diet, created for those with epilepsy consisted of getting about 75 percent of calories from sources of fat (such as oils or fattier cuts of meat), 5 percent from carbohydrates and 20 percent from protein. For most people a less strict version (what I call a “modified keto diet”) can still help promote weight loss in a safe, and often very fast, way.
However, our glycogen supplies in the liver and muscle are quite limited, providing only an 8-12 hour emergency supply. So during a fast, or starvation, or on a diet providing no carbohydrates in any form, we quickly run out of glycogen. In this situation, through a variety of neural and hormonal signaling, our fat cells, or adipocytes, begin releasing free fatty acids into the blood stream. These fatty acids can in turn be used by our cells in the alternate ATP producing process of beta oxidation.
Editors responded with disbelief, claiming the results couldn’t be real since a non-toxic nutritional therapy could never be useful against advanced cancer. I found the logic, “it couldn’t be true because it couldn’t be true” perplexing, for editors of scientific journals. In any event, the book would finally be published, in a rewritten and updated form, in 2010.
Everyone talks about upping their fats… I do not think that is the key to sweeping LDL out of the system. Upping cruciferous fiberous veggies… the fiber, vitamins and minerals contained in veggies bind with the LDL and move it on out. You would have to eat literally a truck load to make any serious dent in your daily carb allowance since most are very low net carb anyways.
The ketogenic diet (also known as the "keto diet") is a high fat, low carbohydrate, and "just enough" protein for growth and maintenance diet. Typically, it follows a ratio of 3-4 grams of fat for every 1 gram of carbohydrate and protein. This means that about 90% of the calories come from fat, requiring those on the diet to eat mostly fatty foods such as butter and cream. Although it may sound terrible, there are many creative recipes that make this a tasty approach. What distinguishes the traditional ketogenic diet from the modified-Atkins diet is the rigorous attention to food intake and limitation on total calories.
Wilder's colleague, paediatrician Mynie Gustav Peterman, later formulated the classic diet, with a ratio of one gram of protein per kilogram of body weight in children, 10–15 g of carbohydrate per day, and the remainder of calories from fat. Peterman's work in the 1920s established the techniques for induction and maintenance of the diet. Peterman documented positive effects (improved alertness, behaviour, and sleep) and adverse effects (nausea and vomiting due to excess ketosis). The diet proved to be very successful in children: Peterman reported in 1925 that 95% of 37 young patients had improved seizure control on the diet and 60% became seizure-free. By 1930, the diet had also been studied in 100 teenagers and adults. Clifford Joseph Barborka, Sr., also from the Mayo Clinic, reported that 56% of those older patients improved on the diet and 12% became seizure-free. Although the adult results are similar to modern studies of children, they did not compare as well to contemporary studies. Barborka concluded that adults were least likely to benefit from the diet, and the use of the ketogenic diet in adults was not studied again until 1999.
The role of gut microbiota has recently been studied for its effect on several diseases, especially those with some inflammatory involvement. Several metabolic pathways are known to be modulated by the gut microbiota. Olson et al. (2018) demonstrated the impact of gut microbiota on the anti-seizure effect of KD. She found that KD modifies the gut microbiota, with a decrease in alpha-diversity and increases in the putatively beneficial bacteria Akkermansia muciniphila and Parabacteroides spp. This microbiota transformation leads to changes in the colonic luminal metabolome, with a decrease in gamma-glutamyl amino acids. This increases the GABA/glutamate content in the brain by decreasing gamma-glutamyl amino acids in the blood (Olson et al., 2018). In an acute electroshock model, it is reported that KD confers protection against seizures. Moreover, KD decreases the frequency of spontaneous seizures in Kcna1 knockout mice (Kim et al., 2015). In summary, changes in the gut microbiota seem to be important for the KD-mediated seizure protection.
With the exception of the myeloma patient, all the other six patients, both Kelley’s and mine, followed a high carb, plant-based diet, replete with frequent servings of fruit and multiple glasses daily of sugar-rich carrot juice. I challenge, for the benefit of science, Dr. Seyfried to match these seven simple straightforward cases. In my experience, no one else has been able to meet the challenge, so I question whether Dr. Seyfried can either.
If you have a history of hypothyroid issues, you may also struggle with unhealthy cholesterol levels as well — and the keto diet can make them even worse. However, for those of you who are being treated for your hypothyroid condition or who have an autoimmune thyroid condition, you may be able to follow the keto diet without any problems. In fact, many keto dieters with autoimmune thyroid conditions have found that the keto way of eating improved their quality of life more than any other diet.
The ketogenic diet for epilepsy (KDE) was developed in the 1920s by Dr. Hugh Conklin in Michigan. But once effective medications were developed, the diet was used less frequently. It has regained recognition and study and is now a standard backup plan for children whose epilepsy symptoms are difficult to control with medication. With over 300,000 children in the U.S. with seizure disorders, this has become an important addition to the arsenal of treatments for epilepsy. Researchers are beginning to see how it might help adults and people with a variety of neurologic disorders.
Ketogenic diets (KDs), being high in fat and low in carbohydrates, have been suggested to reduce seizure frequency in people with epilepsy. At present, such diets are mainly recommended for children who continue to have seizures despite treatment with antiepileptic drugs (AEDs) (drug‐resistant epilepsy). Recently, there has been interest in less restrictive KDs, including the modified Atkins diet (MAD), and the use of these diets has extended into adult practice. This is an update of a review first published in 2003 and last updated in 2016.
For many years, LDL-C tests have been used as the primary method of measuring LDL in the blood. It is cheaper and easier to measure. Recent research has called into questioning how effective LDL-C is compared to LDL-P in precisely assessing cardiovascular risk. After reviewing cross-sectional data, a recent peer-reviewed paper from the world-renowned Framingham Heart Study stated that
Cyclical ketosis means you’re sometimes in ketosis and sometimes aren’t. A few days each week—the night before workout days to build glycogen stores in your muscles—try increasing your intake of berries, higher complex carb veggies (like sweet potatoes), and non-gluten grains. It might knock you out of ketosis temporarily, but it also provides a wealth of nutrients to keep you lean, healthy, and happy. This is also called flexible ketosis, which creates metabolic flexibility—the holy grail of metabolism management. I’ve also talked about cycling ketosis with intermittent fasting, which provides a win-win strategy to reach your health goals.
As the Atkins diet makes abundantly clear, problem foods like gluten and dairy can slip into the strictest low-carb or keto plans. I often see patients "doing keto" with massive amounts of cheese or processed meats full of fillers, which is a terrible idea. These potential top food sensitivities increase inflammation and create problems with gut permeability, leading to leaky gut syndrome.
As the authors write, “the protocol was not designed to reverse tumor growth or treat specific types of cancer.” The researchers also acknowledge the patient numbers were too small to allow for meaningful statistical evaluation, even for the avowed purposes. Overall, the discussion centers on the practicalities of implementing the diet and the results of the PET scans.
The "classic" ketogenic diet is a special high-fat, low-carbohydrate diet that helps to control seizures in some people with epilepsy. It is prescribed by a physician and carefully monitored by a dietitian. It is usually used in children with seizures that do not respond to medications. It is stricter than the modified Atkins diet, requiring careful measurements of calories, fluids, and proteins. Foods are weighed and measured.
Like any normal tissue or organ, in a tumor these cancer stem cells generate a variety of cell types that can mature to some extent, but the stem cells remain always primitive, undifferentiated, capable of replicating endlessly, capable of killing eventually. Most standard therapies fail, Dr. Wicha and his associates believe, because they attack the more mature tumor line, not the essential tumor stem cells, the actual engines of cancer creation.
Tumors did not progress at all at all in the five patients that successfully completed the ketogenic trial. This is a positive outcome given the advanced stage of their cancer. Additionally, some of these patients experienced favorable changes in glucose, HDL:LDL ratio, triglycerides, and healthy levels of weight-loss. These findings further support the healthy impact a ketogenic diet may have on cancer.
Along with slashing carbs, a ketogenic plan also calls for limiting your protein consumption. If you know your macronutrients, you recognize that cutting carbs and restricting protein means seriously upping your fat intake. And that’s exactly what a true ketogenic diet entails. “You’d want healthy fats to account for about 80% of your calories, and protein around 20%,” Westman says. (For comparison’s sake, the average American gets roughly 50% of her calories from carbs, 15% from protein, and 30% from fat, per the CDC.)
